Red stems

[nmbfer8971]

Hi is it normal for clones I bought from the same dispensary but different strains for the stems to start to turn a purple pink color. The stems going off into the leaves first started to change but now it is the main stems as well that are turning. I looked it up and it could be from genetics but if it isn’t what could it be. So far out of the 8 clones about half are turning and more seem like they are to. I have checked my ph and it ranges from 5.5 to 6.5 in all the soils. I placed a cup of water in my tent to raise the humidity and it now stays around 55%. I have had the clines for over a week and when I got them they were from 10-14 days old. Please help

if you're growing in soil and not coco then 5.5 is way too low and it's likely phosphorus deficiency

[nmbfer8971]

if I am growing in soil what should the ph be at

[Potted]

6.5 is best for soil

could also be due to cold. what are your temps?

[nmbfer8971]

My temps have been a bit lower like 69 degrees but it was usually at 75. Is there any cheap solutions on making it warmer I lowered the light if that should help it raise the temp

Also what strains? Are the ones affected most in the 5.5 PH soil?

[nmbfer8971]

I am growing 2 purple punch, blue cookies, mango og, jack herer, dos i do, and 2 unknowns

Thanks for the picture and information. Since my ph is on the low side is there things I can do to raise the acidity like putting in coffee grinds or do I have to buy something

If you use coffee grounds to raise PH, they need to be used before you make coffee with them, or "unwashed". Washed grounds are a good source of N. I have used apple cider vinegar, sulfur (very slow), one can use citrus juice, sulfuric acid and many other things. Or you can buy something, your choice...I cut in pete moss (PH 4.5) to get my soil from 8.4 to 7.0
